1 Claim.

This invention relates to radiators for use in cooling systems of motorvehicle internal combustion engines and has for the primary object theprovision of a device of this character which will be inexpensive tomanufacture and may be readily repaired and will have maximum coolingcapacity for the liquid of the cooling system.

With these and other objects in View, this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding o-f our invention, reference is to be hadto the following description and accompanying drawing, in which Figure lis a front elevation illustrating a radiator constructed in accordancewith our in- Vention.

Figure 2 is a fragmentary sectional view taken in the line 2 2 of Figure1.

Figure 3 is a fragmentary sectional view taken on the line 3 3 of Figure1.

Figure 4 is a perspective View illustrating one of the air passageunits.

Referring in detail to the drawing, the numeral I indicates a radiatorcasing of any conventional design and constructed to have the usualwater chambers 2 at the upper and lower ends thereof connected by awater passage 3 30 including front and rear walls 4 and 5. The

water gravitates from the upper chamber to the lower chamber by way ofthe passage 3 and the front and rear walls 4 and 5 of said passage areprovided with a plurality of substantially ovalshaped openings in whichare removably mounto ed air passage units 6 of substantially tubularshape. The openings of the walls 4 and 5 and units 6 are arranged insuperimposed rows, the units of one row being arranged in staggeredrelation to the units of the row adjacent thereto. The units projectbeyond the front and rear walls 4 and 5 and flanges 1 are formed on thewalls 4 and 5 about the openings to form seats for the units 6 and saidunits are secured 45 to the front and rear walls at the openings bysolder. The units 6 are arranged horizontally and air is adapted to passtherethrough with the water passing upon the exterior thereof. Also, thewater may pass through said units by a series of tubes 8 traversing eachunit. The tubes will be contacted by the air passing through the unitsso that said air may readily absorb heat from the tubes and consequentlylower the temperature of the water passing through the tubes. The airalso absorbs heat from the walls of the unit so that the watercontacting with the exterior walls of the units will be lowered intemperature.

One end of each unit is bent upon itself to form an exterior reinforcingflange 9 which will abut the front wall 4 While the opposite end of theunit is bent upon itself to form an internal reinforcing flange l0. Theflanges 9 and l0 thus formed on the unit will permit the unit to bereadily removed from the front and rear walls when the solder securingthe front and rear walls to said unit is removed. This arrangementpermits any one of the units to be readily removed when damaged andreplaced by another, consequently materially reducing the cost ofrepairing the radiator when defective or damaged.

Opposite walls of each unit are crimped or bent inwardly to form spacedinternal ribs Il acting as air delectors. The air passing through theunits striking the ribs is deflected against the tubes assuring quickerand better cooling of the water passing through the tubes.

Having described the invention, we claim:

A radiator comprising a casing including upper and lower water chambersconnected by a water passage having front and rear walls provided withrows of openings with the openings of one row arranged in staggeredrelation to the openings of the adjacent row, air passage unitsextending through said openings and secured to the front and rear walls,water tubes traversing each unit so that air passing through the unitsmay contact with the tubes, said units having opposite walls thereofprovided with spaced elongated oifsets to form grooves arrangedexteriorly of the units and to provide ribs interiorly of said units fordeflecting the air passing through` the units against the tubes, flangesformed on the front and rear walls about the openings and forming seatsfor the units, each unit having one end bent upon itself to form anexternal ange to abut the front wall and its opposite end bent uponitself to form an internal reinforcing flange.
